The Major


The central intellectual challenge of the Environmental Studies (EVST) major is to combine the knowledge and diverse perspectives of the humanities, social sciences, and natural sciences in order to help solve environmental problems that we face today. Environmental Studies is an interdisciplinary major whose focus is to prepare the best and the brightest students for solving environmental problems in the future.

This major is grounded in chemistry, biology, and math, and is then combined with humanities and social science courses that focus on the environment. From this broad foundation, students can build their own areas of concentration and decide on their senior research. Many Environmental Studies graduates continue their career development by enrolling in top tier professional and graduate schools. studying law, business, medicine, planning or public health, as well as academic fields such as ecology, geology, economics, and history.


Prerequisites and Application to the Major


Students interested in becoming Environmental Studies majors are encouraged to complete the prerequisite courses by the end of their sophomore year, however it is not a requirement to have all of them completed at the time of application. In general, the requirements are:

  1. Two semesters of college chemistry or AP equivalent
  2. One semester of college biology or AP equivalent
  3. One semester of college lab or field experience
  4. One semester of college physics, math, statistics or AP equivalent

Application to the Major

If you are a sophomore interested in applying to the Environmental Studies major, please submit the following information and materials to the Environmental Studies Program Manager (studies.environment@yale.edu).

Recommendation letters are not required.


Requirements for the Environmental Studies Major

A total of 12.5 - 13.5 course credits, in addition to the prerequisite courses, are required for the major. They include 4 core courses, a junior seminar, two terms of the senior seminar, and 6 concentration courses. These courses must be taken for a letter grade. A summary of requirements for the major can be downloaded here.

See the Yale Blue Book Online for course availability, times and descriptions. Search under "Environmental Studies" for a list of current or recent course offerings in Environmental Studies.

Core Courses

Majors must take at least 2 core courses from both the humanities and social sciences (Group A) & the environmental and natural sciences (Group B). Core courses can fulfill Yale College distributional requirements.

Group A: Humanities and Social Sciences

  • EVST 120: Introduction to Environmental History. (Paul Sabin) Survey of interactions between people and natural environments in North America from precolonial times to the present, including ecological, political, cultural, and economic dimensions. The rise of modern conservation and environmental movements; development of public policy.

Pleistocene extinctions; transition from hunting and gathering to agriculture; origins of cities, states, and civilization in Mesopotamia and Egypt; adaptations and collapses of early Old and New World civilizations in the face of environmental disasters; the destruction and reconstruction of the New World by the Old.
  • EVST 255: Environmental Politics and Law. (John Wargo) Exploration of the politics, policy, and law associated with attempts to manage environmental quality and natural resources. Themes of democracy, liberty, power, property, equality, causation, and risk. Case histories include air quality, water quality and quantity, pesticides and toxic substances, land use, agriculture and food, parks and protected areas, and energy.
  • EVST 340: Economics of Natural Resources. (Robert Mendelsohn) Microeconomic theory brought to bear on current issues in natural resource policy. Topics include regulation of pollution, hazardous waste management, depletion of the world's forests and fisheries, wilderness and wildlife preservation, and energy planning.
  • EVST 345: Environmental Anthropology. (Michael Dove) History of the anthropological study of the environment. The nature-culture dichotomy, ecology and social organization, methodological debates, and the politics of the environment.

Group B: Environmental and Natural Sciences

  • EVST 201 & 202L: Atmosphere, Ocean and Environmental Change. (Ronald Smith) Physical processes that control Earth's atmosphere, ocean, and climate. Quantitative methods for constructing energy and water budgets. Topics include clouds, rain, severe storms, regional climate, the ozone layer, air pollution, ocean currents and productivity, the seasons, El NiƱo, the history of Earth's climate, global warming, energy, and water resources.
  • EVST 223: General Ecology. (David Vasseur and David Post) The theory and practice of ecology, including the ecology of individuals, population dynamics and regulation, community structure, ecosystem function, and ecological interactions at broad spatial and temporal scales. Topics such as climate change, fisheries management, and infectious diseases are placed in an ecological context.

Junior Seminars

Majors must complete 1 junior level seminar course from the offerings that has been approved by the DUS. You may take this seminar during any year, not just the junior year. Seminars should provide the following:

1. Broad exposure to the academic literature

2. An extensive writing requirement (literature review, primary source based research paper, prospectus development)

3. Exposure to research methods

A list of possible methods courses for 2014-2015 can be found here.

Concentration Courses

Students plan their concentration in consultation with the Director of Undergraduate Studies. A concentration is defined as six courses that provide depth in a field of interest; four courses should be intermediate and upper level electives from a single department or program, and at least two additional electives from relevant disciplines outside the immediate area of concentration forming a coherent area of study. Because students work with the DUS to define the concentration courses that best suit their academic direction, concentration courses vary. A list of possible concentration courses for the most popular concentrations can be found here.


Senior Seminar and Essay

Seniors are required to take two semesters of Senior Research (EVST 496a and 496b) in which they work on their essay under the supervision of a faculty advisor. Seniors pursuing a double major may opt for a single term of the colloquium, but this must be approved by the DUS in advance. For examples of past senior essay topics, visit the Student Research section of our website. For a copy of the Senior Essay Handbook, click here.

  • EVST 496: Senior Research Project and Colloquium. Independent research under the supervision of members of the faculty, resulting in a senior essay. Students meet with peers and faculty members regularly throughout the fall term to discuss the progress of their research. Projects should offer substantial opportunity for interdisciplinary work on environmental problems.

Faculty Advising

Environmental Studies students are expected to work closely with Yale faculty from various departments. Faculty advisors share responsibility with the DUS for advising students on their course selection, graduation requirements, and most importantly on their senior research project. The faculty advisor is also a valuable mentor to students during and after their education at Yale by aiding students in planning their curriculum, providing career advice, and writing recommendations for students.
